Uncomfortable aircrew seating is more than just a nuisance, it has the potential to produce a cumulative trauma which can significantly affect attention, information processing, and task performance to the extent of interfering with mission completion or contributing to mishaps. Yet, for decades uncomfortable seating has endured as an aircrew complaint with little progress made toward resolving it. Aircraft design techniques have steadily progressed, but the method for ascertaining seating pressure issues has remained, unfortunately, the same: simply ask aircrew where it hurts and hope some cushion changes work. Currently, there exist sensor technologies which potentially can economically and effectively address this problem by reducing the comfort analysis to the examination of an objective, quantitative pressure map. This technical note discusses the brief history of seat pressure measurement research, enumerates some of the technologies that are available that can be applied to the problem, and finally, describes a seated pressure measurement demonstration which shows the power of the approach for maximizing comfort.
机组人员座椅不舒适不仅是个麻烦事，还可能产生累积性创伤，这会严重影响注意力、信息处理能力和任务表现，甚至干扰任务完成或导致事故发生。然而，几十年来，座椅不舒适一直是机组人员的投诉问题，在解决这一问题上进展甚微。飞机设计技术不断进步，但确定座椅压力问题的方法却不幸地依然如故：只是询问机组人员哪里疼，然后寄希望于更换一些靠垫能解决问题。目前，存在一些传感器技术，它们有可能通过将舒适性分析简化为对客观、定量压力图的检查，经济有效地解决这个问题。本技术说明讨论了座椅压力测量研究的简要历史，列举了一些可应用于该问题的现有技术，最后描述了一个坐姿压力测量演示，展示了这种方法在最大化舒适性方面的作用。
